OBJECTIVE: The aim of study was to analyze obstetric and neonatal causes of Korean neonatal deaths. METHODS: The study subjects are a cohort of infants who were born during 1996 and who died before their first birthday. The data were collected through three stages of the study: the collection of existing data, a national infant mortality survey at medical facilities, and data integrating and adjusting process. The sources of existing data were health insurance data and the resident registration data. The National infant mortality survey was conducted by both 'Ministry of Health and Welfare' and 'Korea Institute for Health and Social Affairs'. 3930 medical and health facilities where obstetrics services are available were surveyed during November 1998. The survey results were computerized to match data sets, and any overlap among different data sets were filtered. Causes of deaths were grouped according to the KCD (Korean Standard Classification of Diseases). Causes of neonatal death were further analyzed using composite causes combining obstetric and neonatal conditions. RESULTS: Causes of 2,433 neonatal death were known out of 2,856 deaths. "Certain conditions originating in the perinatal period" comprised 77.1% of neonatal death, being the most common cause. The next common cause was 'congenital malformations, deformations and chromosomal abnormalities', constituting 15.7% of neonatal death. Among the 'certain conditions originating in the perinatal period', 'respiratory distress of newborn' constituted 17.1% of neonatal deaths and 'disorders related to short gestation and low birth weight', constituted 15.6% of neonatal deaths. Neonatal sepsis constituted 14.8% of neonatal death. Among congenital malformations 'congenital malformation of the heart' was most common, constituting 6.2% of neonatal death. 'Certain conditions originating in the perinatal period' was more important cause of preterm neonatal death. Of the related maternal condition, idiopathic preterm birth, multifetal pregnancy, premature rupture of the membranes and hypertensive diseases during pregnancy were common conditions. Congenital malformation was the most important cause of term neonatal death. CONCLUSION: Prematurity-related condition was more important cause of preterm neonatal death while congenital malformation was the most important cause of term neonatal death.

We present the first case report of fragile X-associated tremor ataxia syndrome (FXTAS) in the Republic of Korea. A 75-year-old male developed progressive gait ataxia, parkinsonism, and a mood disorder. Magnetic resonance imaging revealed T2 high signal intensity within the middle cerebellar peduncles. Analysis of the fragile X mental retardation 1 gene revealed a CGG trinucleotide repeat number of 136. FXTAS should be considered when a patient has atypical parkinsonism, cerebellar ataxia, and specific MRI abnormalities.

It has recently been shown that nearly all cancers from hereditary nonpolyposis colorectal cancer syndrome (HNPCC), as well as a subset of sporadic colorectal cancers, have DNA replication errors (RER) at repeated sequences distributed throughout their genome. These RER-positive cancers had pathological characteristics of more frequent exophytic growth, large size and poor differentiation. However, the histogenesis and immunohistochemical characteristics of these RER-positive cancers are not known. The poorly differentiated colorectal carcinomas are heterogenous group of neoplasms that differ in their histologic appearance and prognosis. We therefore examined RER from 69 sporadic colorectal carcinomas of poor differentiation and detected in 23 cases (33%). The pathological features of RER-positive cancers differed from those without RER. The RER-positive cancers had marked preponderance of proximal location (16/23, 70%, vs. 20/46, 43%, p< 0.04), no glandular differentiation with intense peritumoral immune response (12/23, 52% vs. 6/46, 13%, p< 0.001). Immunohistochemically, most of the RER-positive cancers were reactive for cytokeratin (22/23, 96%) and CEA (17/23, 74%), and negative for NSE (2/23, 9%), chromogranin (3/23, 13%) and synaptophysin (0/23, 0%). In comparison to 46 RER-negative tumors, RER-positive cancer had less frequent CEA expression (17/23, 74% vs. 44/46, 96%, p = 0.01). We conclude that the RER-positive colorectal carcinomas have histologic characteristics of predominantly solid, poorly differentiated adenocarcinomas with intense peritumoral reaction and the tumors should be distinguished from neuroendocrine carcinomas and other more aggressive non-glandular tumors of the colon.

Transient synovitis of the hip is non-specific inflammation and self limited condition, which is most common cause of painful limping in children under 10 years of age. Ultrasonography presents some merits, simple, rapid, non-invasive, low cost, repetitive to assess soft structures in and around the hip joint compared to other diagnostic methods. We prospectively studied 32 cases of unilateral transient synovitis at OPD from Jan. 1988 to Oct. 1989 using 5-7.5 MH, probe ultrasonography. 2-times serial check up in symptomatic and asymptomatic stage about capsule thickness and bone-capsule distance in 3 different positions of the both hips were performed for comparision. The following results were obtained; 1. Boys were 25 cases (78%) and 26 cases (83%) were between 3 and 7 years old of age. 2. Bone-capsule distance in ultrasonography revealed abnormal increase in 72%. 3. External rotation position showed wider bone-capsule distance than other position. 4. Capsule thickness was 3.3mm in diseased and 3.0mm in sound, 0.3mm decrease after treatment. 5. Bone-capsule distance was 4.5mm in symptomatic stage, 2.7mm in asymptomatic stage, 1.8mm decrease after treatment in averge.
